Post Office Box 2096 Re: Authority of a local taxing unit to waive 

Big Spring, Texas 7972 1-2096 penalties and interest on taxes that became 

delinquent as a result of an act or omission of an 

officer, employee, or agent ofthe appraisal district 

(RQ-0555-GA) 

Dear Mr. Thomas: 

On behalf of several local taxing units you ask the following question: 

May local taxing units waive penalties and interest pursuant to 

Property Tax Code Section 33.01 1 (or any other provision of the 

Property Tax Code) on delinquent ad valorem taxes which became 

delinquent as a result of an act or omission of an agent of the 

appraisal district, which were paid in full (including all accrued 

penalties and interest) within 21 days after the taxpayer knew or 

should have known of the delinquency, when a written request for 

such waiver was received within such 21 day period, but not within 

the 18 1 st day after the delinquency date?' 

Your request relates to a specific property, which is subject to ad valorem tax by four political 

subdivisions. See Request Letter, supra note 1, at 1. The tax assessor for each taxing unit is required 

to mail tax bills to persons in whose names property is listed by October 1 or as soon thereafter 

as practicable. See TEX. TAX CODE ANN. $ 31.01(a) (Vernon Supp. 2006). Subject to narrow 

exceptions, "taxes are due on receipt of the tax bill and are delinquent if not paid before February 

1 of the year following the year in which imposed." Id. 5 3 1.02(a). If a tax bill is mailed after 

January 10, the delinquency date will be postponed until a certain date after the date of mailing to 

allow for paying the taxes before they become delinquent. See id. $3 1.04(a). But if no bill is mailed 

to the taxpayer because his address is unknown, the February 1 delinquency date will still apply. See 

Aldine Indep. Sch. Dist. v. Ogg, 122 S.W.3d 257,274-75 (Tex. App.-Houston [lst Dist.] 2003, no

§ 3 1.0 1 (g) (Vernon Supp. 2006) (failure to send or receive the tax bill required by section 3 1.0 1 

"does not affect the validity of the tax, penalty, or interest, the due date, the existence of a tax lien, 

or any procedure instituted to collect a tax"). Tax Code section 33.01 provides for penalty and 

interest on delinquent taxes. See TEX. TAX CODE ANN. 5 33.0 1 (Vernon 2001). 

You inform us that taxes became delinquent on the property in question for the years 2003, 

2004, and 2005 as a result of an act or omission by an agent of the appraisal office. See Request 

Letter, supra note 1, at 1. The taxpayer became aware of the delinquency on or about October 15, 

2006, and paid under protest the delinquent taxes for all three years, including all accrued penalty 

and interest, on October 30,2006. See id. at 1-2. The taxpayer included with the payment a written 

request for a waiver of penalties and interest. See id. at 2. You ask whether Tax Code section 

3 3.0 1 1 may authorize the taxing units to waive penalties and interest. See id. at 1-2. This provision 

states in part: 

(a) The governing body of a taxing unit: 

(1) shall waive penalties and may provide for the waiver of 

interest on a delinquent tax if an act or omission of an officer, 

employee, or agent of the taxing unit or the appraisal district in which 

the taxing unit participates caused or resulted in the taxpayer's failure 

to pay the tax before delinquency and if the tax is paid not later than 

the 2 1 st day after the date the taxpayer knows or should know of the 

delinquency[.] 

TEX. TAX CODE ANN. § 33 .011 (a)(l) (Vernon Supp. 2006); see also id. 5 33 .011 (b) (waiver of 

interest and penalties if a tax bill is returned undelivered to the governmental body, subject to 

additional conditions), (h) (waiver of interest and penalties if a tax payable by electronic funds 

transfer was delinquent because of an error in the transmission). 

The section 33.01 1 waiver provisions are, however, subject to the following limitation: 

A request for a waiver of penalties and interest under 

Subsection (a)(l), (b), or (h) must be made before the 18 1 st day after 

the delinquency date. . . . To be valid, a waiver ofpenalties or interest 

under this section must be requested in writing. Ifa written request 

for a waiver is not timely made, the governing body of a taxing unit 

may not waive any penalties or interest under this section. 

Id. 5 33.01 l(d) (emphasis added). The italicized language of section 33.01 1 (d) was adopted by an 

act of the Seventy-ninth Legislature that included the following transition clause: 

Section 33.01 1, Tax Code, as amended by this Act, applies 

only to a request for a waiver of penalty or interest made on or after 
The Honorable C.E. "Mike" Thomas, I11 - Page 3 (GA-0548) 

the [September 1, 20051 effective date of this Act. A request for a 

waiver made before the effective date of this Act is governed by the 

law as it existed immediately before the effective date of this Act, and 

the former law is continued in effect for that purpose. 

Act of May 29,2005,79th Leg., R.S., ch. 1126,s 29(g), 2005 Tex. Gen. Laws 3717,3730. See also 

id. § 15, at 3723 (amending Tax Code section 33.01 l(d)); id. 30, at 373 1 (effective September 1, 

2005). 

Section 33.01 l(d) of the Tax Code, as amended in 2005, applies to the taxpayer's written 

request for a waiver of penalties and interest made on October 30,2006. See id. 29(g), at 3730. 

You have stated that the taxpayer's written request for a waiver of penalties and interest was not 

made before the 18 1 st day after the delinquency date for each of the three years in which taxes were 

delinquent. See Request Letter, supra note 1, at 2. The plain language of section 33.0 1 1 (d) compels 

us to conclude that the taxing units may not waive penalties or interest on the delinquent taxes. 

You ask whether any other statute or constitutional provision authorizes taxing units to waive 

the penalties and interest on this account. See id. at 1-2. Because you provide no specifics about 

the act or omission causing the taxpayer's failure to pay his taxes on time, we will answer your 

questions in general terms. 

We note initially that a taxpayer is charged with knowledge of the law. See Mexia Indep. 

Sch. Dist. v. City of Mexia, 133 S.W.2d 118, 121 (Tex. 1939); see also Texaco, Inc. v. Short, 454 

U.S. 5 16, 532 (1 982) (property owners are especially charged with knowledge of laws relating to 

taxation). Moreover, a political subdivision may not waive penalties and interest imposed by statute 

absent statutory authority. See Tex. Att'y Gen. LO-93-58, at 2 (special district may not waive 

penalties and interest due on delinquent taxes); see also Tex. Att'y Gen. Op. No. JM-74 (1983) 

at 2 (appraisal district may not waive penalties and interest imposed upon taxing units that are 

delinquent in paying their share of the district's expenses). Tax Code section 41.41 entitles a 

property owner to protest certain actions before the appraisal review board, including "any other 

action ofthe chief appraiser, appraisal district, or appraisal review board that applies to and adversely 

affects the property owner," and section 41.41 1 authorizes a property owner to "protest before the 

appraisal review board the failure of the chief appraiser or the appraisal review board to provide or 

deliver any notice to which the property owner is entitled." TEX. TAX CODE ANN. $8 41,41(a)(9), 

.411(a) (Vernon 2001). A notice of the protest must be filed with the appraisal review board 

according to the applicable deadlines of section 41.44. See id. 41.44 (Vernon Supp. 2006); see 

also id. 5 41.44(c) (notice of protest authorized by section 4 1.4 1 1 must be filed before the date when 

the taxes become delinquent). Whether any remedies are available to a particular taxpayer depends 

on the facts of that case.

SUMMARY 

Tax Code section 33.0 1 1 requires a taxing unit to waive 

penalties and authorizes it to waive interest on a delinquent tax if the 

taxpayer's failure to pay the tax before delinquency resulted from an 

act or omission of an officer, employee, or agent of the taxing unit or 

the appraisal district in which the taxing unit participates and if the 

tax was paid not later than the 21 st day after the date the taxpayer 

knew or should have known of the delinquency. Section 33.01 1 

requires such a request for a waiver of penalties and interest to be 

made before the 18 1 st day after the delinquency date.
